.. 3 I c i y teams, cic e- WELL The invention relates to a trap or separator forfltreating liquids such asfsewage; and particularlyd ainage, containing two types of contamie nating substances, for instance solids and flight liquids. c 1 It is the obJ'ect of the present invention to control the operation of theseparating equipment and to interrupt the discharge of the sewagefbv the weight of the solid contaminations; f

,Itis a further object ofthe invention. to ekert this control by either of the twogroups of the contaminations above referred to. i i

It is also the objector this invention to construct the means by'whlch this control attained It'is a l'urther object oithisinventionto m. duce a unitfor sewage separators whereinjthe 'contaminations of the sewage accumulate and. which may be used without constructional changes for any type of] sewage separators independently upon their size or shape.

Further. objects andadvantags of my improved sink water trap or sewage separator will be apparentfrom the following detailed descrip-.

tion in connection with the accompanying drawing illustrating by way of example onemodifica tion of the invention.

In the drawing,

Fig. 1 is a verticalfsectional: view a sink tion is embodied, w w c Fig. 2 is, aplan view thereof... i

watertrap or oil separator in which my invcn- Fig.j3is a vertical elevation. of the removable.

interior parts of the separator, c c Fig. 4is an enlarged sectional detail. 3

f'l'heseparatorillustrated in the'drawing comprises tank l5, provided with a seal l6, which i has a passage 36 at its lower end adapted to, hold aseallng liquid column 20, .ZIinside the tank, 40 The tank I5 is provided with a feedv pipe 5 used at the same time asa separating space.

coming from a floor drainer othersources, with a water outlet channel 11; leading to the sewer line, with a connection tubemlfi for a pump for drawing off water or oil Zly'and with a tube 22 as an outlet for conveying oil toa separate oil storage reservoir. i i i The up er part of tank I5 comprises an extension 1 whichis provided withsuitable means like bands or flanges 21 tohold the-solids collector or bucket 6 and its opening 33 in alinement with the feeding pipe 5. The "usual vent pipe I8 is connected by pipe l8 with thesewer line H to prevent syphoning. The bucket 5 with its handle 30 is removable through' the. top of extension I which is {provided with a removable cover 8 and with;handle 9; cover 8 is in alinementwitnthe' garage floor. i A tube I2 is inserted into the bottom l0 of 1 collector "6. This tube forms a passage'iromthe collectorTintd receptacle .13; Receptacle I3 is situated within floating chamber 23-fwhich is located underneath the solids collector 6. A controlling member consisting of a valve disc and a stern 24 locatedintube l The upper end of the tube forms a seat forvalve 24, 25 in its closed position; in its openpositionthe valve is supported on the bottom of chamber l3.

"The latter is preferably attached'to cover l3 of "a floating chamber 23 (Figs. land 4) which is providedat its top with overflow openings 31-.

Screws 34 secure cover l3 to the wall of recepta c'le 23 andconnect receptacles l3 and 23. Cover I3" is provided with a vent32. 26 indicates'a cage suitably attached to bucket 6 in order to guide chambers 23 and I3in their movements and to enable them to be inserted and removed togetherwith'thebucket 5 and the other parts shown in Fig. 3 as 11mm. T

The operationof the separatoris asffollows: Tank l5 filled with" drainage waterup to the lower leveloutlet Il. As soonasthe unit shown in Fig. 3 is positioned in the tank, the

, float ascends toits upperiposition until stops 35 hit the bottom of bucket 5. i The garage drainage 1 enters inthe' direction of-thearrowinto tank l5 through feed tube 5 (Fig."D and flows through inlet 33 into the solids collecting bucket 61 The liquid accumulates in bucket 6 untill'evel I i is reachedy then it overfiows' into outlet conduit I! in the directionof'the arrows. "The solids containedin the. entering liquidsettle on the bottom ill of receptacle 6 to be periodically removed; when. they are not removed they fall downwards through tube 12 into chamber l3 and accumulate therein as shown by M. Whenthe weight of the. solids accumulated at M counteracts the buoyancy of the floating receptacle l3 whichhas been lifted upward during the placement of unit A into the drainage filledseparating, tank floating receptacle 23 s inks downwards. At the same time valve 24, 25 is lowered closing the admission to tube 12. ,The sewage fills up drainage tube5 and flows from there upon the floor of the garage indicating that solids collector 6 should be cleaned and removed for this purpose.

It will be readily understood that by inserting unit A intothe tank l i of the waste watertrap,

Fig. l, the chambers 23 and I3 will be keptafloat' the cage 26 until the lugs 35 of the cover l3 touch the bottom of bucket 6 in which position stem 24 of valve touching the bottom of chamber l3 will keep the tube [2 open.

The unit A is removed by opening cover 8 and lifting the unit A through extension "I from tank I5. The solids are removed from the unit and the same is again introduced into the separating tank; the floating receptacle 23 is lifted upwards by its buoyancy together with valve 24, 25 and the inflow of the sewage commences again.

The light liquids containing sewage overflowing the upper edge of tube l2 flows in the direction of the arrows over cover 13' into the tank l5. The light liquids which are separated by their lower specific weight from the sewage water accumulate on the upper surface of the-water as layer 2!. As soon as a suflicient amount of light liquids is accumulated to reach openings 3| it flows into the inner space of the floatingreceptacle 23.. Hereby this receptacle with valve 24, 25 is. lowered and further admission of sewage into the separator is interrupted. a

Unit A is removed in the manner described above and the light liquids areemptied out from tank I and receptacle 23. Then the unit A is. again introduced into the. separating tank and the inflow of the sewage and. the separation of the contaminations is commenced again. Hence, it is apparent that the discharge of the separator may be automatically controlled by the accumulation of contaminations which have a higher specific weight, than the sewage water and also by the accumulation of the light liquids.

The great advantage of my invention consists therein that the elements controlling theautomatic-operation of the discharge arefconstructed as asingle unit to be inserted and removed through the cover opening or manhole of a sink water trap or separator. 1

This unit can be, constructed on a standard basis. It can be used for any type of separating tanks independently upon their size. or shape. This could not be accomplished up to now because the wallsof the separating tank were used as a guiding means for the floating receptacle.

Various changes and modifications may be madetothe details contained inthe description of my-invention for the separation of liquids containing contaminationswhich. have a higher and a lower specific weight than water, without departing. from the broader spirit and scope thereof, asset forthin the following claims.
